class eradiate.scenes.integrators.PathIntegrator(id='integrator', max_depth=None, rr_depth=None, hide_emitters=None)[source]#

Bases: eradiate.scenes.integrators._path_tracers.MonteCarloIntegrator

A thin interface to the path tracer kernel plugin.

This integrator samples paths using random walks starting from the sensor. It supports multiple scattering and does not account for volume interactions.

Parameters

  • id (str, optional, default: "integrator") – User-defined object identifier.

  • max_depth (int, optional) – Longest path depth in the generated measure data (where -1 corresponds to ∞). A value of 1 will display only visible emitters. 2 computes only direct illumination (no multiple scattering), etc. If unset, the kernel default value (-1) is used.

  • rr_depth (int, optional) – Minimum path depth after which the implementation starts applying the Russian roulette path termination criterion. If unset, the kernel default value (5) is used.

  • hide_emitters (bool, optional) – Hide directly visible emitters. If unset, the kernel default value (false) is used.

Fields

  • id (str or None) – User-defined object identifier.

  • max_depth (int, optional) – Longest path depth in the generated measure data (where -1 corresponds to ∞).

  • rr_depth (int, optional) – Minimum path depth after which the implementation starts applying the Russian roulette path termination criterion.

  • hide_emitters (bool, optional) – Hide directly visible emitters.

kernel_dict(ctx)[source]#

Return a dictionary suitable for kernel scene configuration.

Parameters

ctx (KernelDictContext) – A context data structure containing parameters relevant for kernel dictionary generation.

Returns

KernelDict – Kernel dictionary which can be loaded as a Mitsuba object.
